The card takes place from Montreal's Bell Centre on November 17. St-Pierre (22-2) has not fought since 2011, when he defeated Jake Shields.

"I'm excited to finally get back in the Octagon and reclaim my spot as the UFC welterweight champion," St-Pierre said. "Carlos Condit is a very tough opponent. I respect him a lot and look forward to fighting him in front of my hometown fans in Montreal."

Condit (28-5) claimed the interim title with a victory over Nick Diaz earlier this year. St-Pierre and Condit are expected to attend a press conference on Thursday to kick-start ticket sales for the event. FightLine will have complete coverage of the press conference on Thursday.
